PAPER-GUIDE roe PRESSES.

To all whom it may concern:

Be it known that I, LEoroLD BAKKE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Guides for Presses, of which the following is a full, clear, and exact specification.

My invention is concerned with paper guides for printing presses, and is concerned mainly with an improvement intended to be applied to side guides, although in part it is concerned with an improvement which is also applicable to front guides.

In side guides, as heretofore constructed, the stop plate has been so mounted when in posit-ion on the feed table that it did not necessarily rest at both corners squarely upon the feed table, especially if the latter happened to have an uneven surface where the stop plate rested, with the result that the paper being fed in might accidentally get under one corner of the stop plate, thereby producing an uneven feed, or possibly catching and tearing the sheet. To remedy this difficulty, I mount the stop plate so that its bottom is free to move to accommodate itself to any unevenness in the feed table, and thus insure both corners resting squarely thereon.

In another feature, my invention may be considered as an improvement. on the in vention covered by my Patent No. 1,011,009, dated December 5, 1911, as I have in the present construction changed the combination therein shown so that the stop plate can be moved against the resistance of the spring only toward the paper, and not in the direction of the feed, the movement in the latter direction being objectionable, as it might result in the accidental displacement of the stop plate.

Finally, my present invention is con cerned with a novel combination of elements whereby the invention shown in my application No. 67 1,28 1, filed January 15, 1912, may be applied as well to a side guide as to the front guide shown in said application.

To illustrate my invention, I annex here to a sheet of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which,

Figure 1 is a top plan view of a portion.

a sectional view, on an enlarged scale, on the line A-A of Fig. 1; Fig. 3 is a view in section on the same scale, on the line 13-13 of Fig. 2; Fig. 1 is a top plan view of the stop-guide end of the device; and Fig. is a view in section on the line CC of Fig. 4.

The sleeve 10, which carries the guide mechanism proper, may be adjustably secured in any desired manner, as by the wing nut 11 cooperating with the bolt 12 upon the slotted supporting bar 13, which can be secured upon the table 14 in any desired position of adjustment by the wing nut 15 cooperating with the customary bolt 16. The mechanism thus far described constitutes no part of my invention.

The sleeve 10, as best shown in Fig. 2, is provided at one end with the aperture or recess 17, in which the adjacent end of the rod 18 is adapted to be guided. The opposite end of the rod 18, which is threaded, as seen, slides freely through a guiding aperture formed in the collar 19 closing the other end of the sleeve 10; and to prevent any possible rotation of the rod 18, I employ some suitable means, such as the pin 20 projecting therefrom and adapted to slide in the longitudinal slot 21 formed in one side of the collar 19, which is held from rotation in the sleeve by the pin 22 passed through the sleeve 10 and into the collar, as shown. The outer end of the collar 19 preferably has the annular enlargement 28, which has on its outer face the series of equidistant grooves 24: which are adapted to be entered by the beveled end of the pin 25 secured in the adjusting nut 26, through which the end of the rod 18 is threaded. This nut 26 is preferably provided with the annular enlargement 27, the periphery of which is milled so that it can be readily turned in securing the desired adjustment of the stop plate, which it will be understood is secured on the outer end of the rod 18. To hold the nut 26 firmly, yet yieldingly, in any desired position of adjustment, I interpose the strong helically-coiled expanding-spring 28 between the inner end of the collar 19 and the washer 29 held in place on the rod 18 by the pin 30.

Vith the construction herein described, it will be obvious that the position of the rod 18 in the sleeve 10, and consequently the exact position of the stop plate carried by the end ofthe rod, can bevery accurately ad usted and secured in any desired position of adjustment by simply grasping. the

milled flange 27 and pulling the rod to the right far enough to disengage the'pin. 25- from the recess 24 which it happens to oc-- cupy. The nutican. thenibe turned in the proper direction as muchasmay be necessary to secure the desired movement of the rod 18, and the accurate ad ustment necessary may be readily obtained in the-manner full'yyse-t out inimy above-mentioned Patent The stop plate 31, instead of being'directly connectedto the end of'the rod 18, is--mount= ed tomove vertically, and also to swing;

upon the supporting plate 32 rigidly secured on the threaded end of the rod 18, andthe vertical movement of the plate '31 is secured by reason of the slightly elongated slot 33' formed therein, through which.

passes't-he screws84, the end' of which is securedin the'supporting"plate32. It is desired to hold this stop plate yieldingly downward, and also sothat-it'can be swung slightly from side to side, and forthis purpose I employ the pair of'helically-coiled expanding-springs interposed between the Jair. of 'lu s or studs 36 )ro'ectin forward b D from the supporting plate and the oppositelyedisposed lugs'37', likewise projecting ends of the lugs 3G'the. small rods 38 which pass through the springs'35, and the'lower. ends of which extend mto'or pass through suitable apertures formed'in the lugs 37 With the construction heretofore described, it will be apparent that the stop plate 31" can not only yield upward, but it can swing-slightly about the screw 34 as a center, so that the lower corners 39'of' said= stop plate can be made to rest on the feed table 14 at any. point in spite of any unevenness that may happen to exist at said point;

With both the springs 35 under equal stress, the central longitudinal axis of the stop plate 31 is in alinement withor parallel to the similar axis of the supportingv plate 32, and if the upper surface of the table 14 were horizontahthese axes would be vertical or perpendicular thereto" I'nmy application No. 671,284, filed January. 15, 1912, I have shown an adjusting. plate to regulate the height of the spring;

guides 40 above the cooperating feed-table surface as applied to a front guide in which the stop plate is rigidly secured to the sup portingplate, and inthe present. application I have shown the same adjusting'plate llltlClifibCliSOattS tube-applicable to the swing ing stop-plate of this novel side guide. To this end,-the-adjusting plate 41 is likewise provided with the slot 42 corresponding .withi the slot. 33, and through which the screw 34 passes. This adjusting plate 41 is 'providediatits lower corners with turnedover edges 43, which cooperate with the vertical edges of" the stop plate 31, but need not embrace 1t, as 1n my prior patent, owing,

to the coaction of the head of the screw-34 with. the narrower slot 42. The spring. guides 40 in my novel' construction are united in' the body portion 44, which is:reduced and turneddown, as seen at 45,.and securedto'the upper'portion of the adjustingplate41 in any desired manner, as by the screws 46. To adjustthe positionof-the' plate 41. (the loweredge of which cooper= ates with the uppersur-faces of the lowerportions. of the spring: guides 40, as explained in my above-mentioned applicamom-,1 provide the offset end47 off thestop plate'31, in which is-rotatably mounted the unthreaded portion of the screw 48,.which is provided with the collar 49 to hold it from. vertical movement. The threaded portion ofthe screw 48 cooperates with the thread= ed a-perture in the'oifset upper end 50 ofthe adjusting'plate-41, and'when said'plate has been moved to any desiredposition of ad justment, by. manipulating the screw 48, it' can. be screwed in said'position by turning down the lock nut 51 againstthe upper face ofthe offset 50:.

Vith the spring guides secured at their outer ends to the adjusting plate 41, and with their lower ends pressed upward against its lower edge, it will be apparent that the spring guides in operation have no movement relative to the plate 41 (as they do in my above-mentioned application), but always move with it, andconseqncntly they might be permanently secured to the Jlate where they engage its lower. edge. 11 fact, there is no need for the guid ing fingers to be springs at all, but they might be a. rigidcasting secured to or formed integrally with the plate 41.

lVhileI" have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it willbe understood that it is cap-able of modifications, and that I do .not'desire to be limited in the interpretation of the following, claims except as may be necessitated by the state of' the prior art.
